Descale the tank
Note
Hard water may cause the formation of limescale, which will reduce the operating
efficiency and may cause early product failure. Failure of the water heater due to
limescale or other deposits would not be classed as manufacturing defect and as such
would not be covered under the terms of the warranty (on page 3).
Note
Before reassembly replace the gaskets. You must order these gaskets at your supplier.
Look at the data plate for the correct ordering information.
To descale and clean the tank:
1.
Decommission the water heater (see 8.8).
2.
Remove the left side plate of the water heater.
Warning
Live cables inside! Switch off the power supply completely (on local isolator) before
removing the left side plate to access the electrical components.
3.
Remove the lowest service cover.
4.
Remove the lowest element cover (1).
